It's the final week of Human CAPTCHA: Round 7 You made it this far… but we’re not going easy on you. One of these is a real photograph of a hot air balloon, the rest is AI-generated. Can you tell which one it is? Respond with Left, Middle, or Right and tell us why below! Submissions close Sat, Feb 28 at 11:59pm UTC. Answers revealed Sunday.

@PerleLabs Left I pick Left because the lighting transition between the balloon and the sky looks natural. There’s no strange halo effect or overly smooth blending. The smaller balloons in the background also scale realistically and don’t show repeated or distorted patterns.
